Description
Technical field
The present invention relates to solar photovoltaic assembly technical field, in particular to a kind of photovoltaic group of diode-built-in
Part.
Background technology
The terminal box that the photovoltaic module of prior art uses, no matter split or single-gang junction box, diode all be place
In terminal box.Such structure causes that terminal box volume is big, and materials are more, cost of idleness.And because diode is in wiring
In box, also it is unfavorable for radiating.Although having there is photovoltaic module structure of the diode not in line box at present, its structure is also
It is existing defects.
As Authorization Notice No. be CN201682236U, a kind of entitled terminal box of solar photovoltaic assembly China specially
Profit, it discloses a kind of a kind of photovoltaic group that bypass diode unit is connected to box portion outside by the groove on box body
Part, although solar photovoltaic assembly disclosed in the patent by diode from box body it is external out.But it still blocks
It is connected on box body, really diode is not arranged on inside photovoltaic module.
As Chinese patent application publication No. be CN102751358A disclose a kind of diode-built-in solar components, use
Chip diode, although it is built-in with inside photovoltaic module, being needed when diode damage needs to change to realize diode
Whole backboard or glass plate are opened to be changed, component can be damaged, it is difficult to operate.
The content of the invention
It is an object of the invention to provide a kind of diode to be built in component, and is easily changed too after diode damages
Positive energy component.
Therefore, the present invention adopts the following technical scheme that：
A kind of photovoltaic module, including front glass panel, solar cell chip arrays, backboard and the line box being arranged on backboard,
Solar cell chip arrays include some solar cell strings being connected in series, it is necessary to be connected with two between two string battery strings of bypass
Pole pipe；One section of busbar is welded on the both positive and negative polarity of the diode in advance respectively, wherein the pole being connected with line box is confluxed
Bar is long busbar；During component stack, the diode that busbar has been welded in advance is connected to need to bypass two by polarity
Between string battery strings；Long busbar is turned up and led to outside component and is attached with line box positive/negative；In diode correspondence position
One perforate is set at backboard；The busbar drawn after being turned up on the diode exports from tapping；The line box is arranged on out
Kong Shang, for sealing perforate；Perforate size can just spill diode and diode both ends welding position.
Further, the busbar same material that the busbar on the both positive and negative polarity of the diode uses with photovoltaic module.
Further, the busbar pad that end connection is turned up with busbar is provided with the line box.
Further, the size of the line box coordinates with the perforate size set at backboard, is covered after the line box installation
Perforate on backboard.
Further, the line box includes positive pole box body, negative pole box and middle box body.
Further, the quantity of bypass diode can be 2 or more than 2, and bypass diode is encapsulated in component.
Further, the backboard uses conventional photovoltaic backboard, or glass plate.
What the present invention realized has the beneficial effect that：
1st, by the busbar being pre-welded on diode both positive and negative polarity, directly diode is built in component；Simultaneously
By the way that the busbar of diode one end turned up into extraction, and the mode of perforate is opened up on backboard or back of the body glass by the one of diode
End is connected with line box, and the position of line box can only cover perforate.It is so follow-up to be damaged in the event of diode, only need
Line box is dismantled, excavates silica gel and EVA, it is possible to changes diode, wire terminal box again after replacing.
2nd, the position of diode is placed due to that need not be reserved built in diode, in line box, the volume of both positive and negative polarity line box can
To be made small, and middle line box is welded due to that need not draw lead-out wire outside component, or can only not needed
One plastic sheet, therefore can greatly save line box materials.
3rd, diode circuit need not be designed in line box, saves the copper sheet of arrangement diode, it is not necessary to consider diode
Radiating, line box volume can further reduce.
4th, built-in diode, is welded a bit of busbar on the two poles of the earth of diode in advance, will during component stack
Busbar connects with busbar in component, and operation is simple and reliable.
5th, after line box volume reduces, the casting glue dosage of silica gel and sealing required for corresponding and component bonding
It can significantly reduce.
If the 6, diode damages, diode is directly changed, it is not necessary to change box body.
In summary, the cost of terminal box can decline to a great extent.
